Sure thing, the 5‑pin sockets are the real heart of the Spectrum. First thing: pull a clean, lint‑free cloth over the board and let it sit for a few minutes to get the dust out. Then use a soldering iron with a fine tip and a little bit of rosin flux on each pin – you want a clean, bright weld, no blobs. If a pin’s bent, you can use a small needle or tweezers to straighten it, but be careful not to nick the copper. For any cracked sockets, replace them with identical parts; a cheap one can be soldered on, but a genuine kit part will keep the aesthetic. When re‑soldering, keep the heat on each pin for no more than a second or two – the chip can overheat fast. Finally, once everything’s soldered, give the board a quick test on a dummy power supply, and you’ll see the green screen flicker to life. Happy hacking!

Green flux is fine, it’s the classic choice and dries nicely. Clear works too, just be sure it’s high‑quality rosin, not that cheap paste that can leave residue. Either way, the key is a little amount on each pin so you get a clean, bright solder. Good luck, and may those pixels stay sharp!
